10. WIRING EXAMPLE

10-1 HOW TO CONNECT WIRINGS

Wire only after removing the control box lid as shown in

Fig. 17, referring to view A.

CAUTION

Be sure to attach power supply wiring and earth wire to the

control box with the clamp.

When doing the wiring, make sure the wiring is neat and

does not cause the control box lid to stick up, then close the

cover firmly. When attaching the control box lid, make sure

you do not pinch any wires.

Outside the air conditioners, separate the weak wiring
(remote controller and transmission wiring) and strong wiring
(earth wire and power supply wiring) at least 50 mm so that
they do not pass through the same place together. Proximity
may cause electrical interference, malfunctions, and break-
age.

A main switch or other means for disconnection, having a

contact separation in all poles, must be incorporated in the

fixed wiring in accordance with relevant local and national

legislation.

Note that the operation will restart automatically if the main

power supply is turned off and then turned back on again.

[ PRECAUTIONS ] 

Refer to the “REMOTE CONTROLLER INSTALLATION

MANUAL” on how to install and lay the wiring for the remote

controller.

See also the “Wiring Diagram plate” attached to the control

box lid when laying electrical wiring.

Connect the remote controller and transmission wiring their

respective terminal blocks.

CAUTION

• Do not, under any circumstances, connect the power sup-

ply wiring to the remote controller or transmission wiring

terminal block. Doing so can destroy the entire system.

[ Connecting electrical wiring, remote controller wiring, 
and transmission wiring ] (Refer to Fig. 18)

• Power supply and Earth wiring

Remove the control box lid.

Next, pull the wires into the unit through the wiring through

hole and connect to the terminal block (3P).

Be sure to put the part of the sheathed vinyl into the control

box.

Penetration area

• Make sure to let a wire go through a wire penetration area.
• After wiring, seal the wire and wire penetration area to prevent 

moisture and small creatures from the outside.

• Wrap the strong and weak electric lines with the sealing 

material (12) as shown in the figure below.

(Otherwise, moisture or small creatures such as insects from 

the outside may cause short-circuit inside the control box.) 
Attach securely so that there are no gaps.
